IOCFR50.59 EVALUATIONS DOCKET NO: 50-272 MONTH: MAY I995 UNIT NAME: SALEM I DATE: 06/10/95 COMPLETED BY: R.HELLER TELEPHONE: 609-339-5I62 The following items were evaluated in accordance with the provisions of the Code of Federal Regulations IOCFR50.59. The Station Operations Review Committee has reviewed and concurs with these evaluations.

I. Design Change Packages (DCP)

IEC-3387, Pkgs I- 3 "EDG IA, B & C Air Receiver Low Pressure Alarms" Rev. 0 -

The purpose ofthis design change is to install two pressure switches each, along with all associated tubing, valves, and wiring for the starting air receivers for Diesel Generators IA, IB & IC. These pressure switches are to provide new low pressure alarms for each of the starting air receivers. These will provide early warning to the operating personnel so that they can take adequate action to mitigate starting air receiver degraded conditions and maintain the receiver pressure adequate for three diesel starts. The Diesel Air Start System and its components, including instruments, are not the subject of any technical specifications or technical specification basis.

There is no reduction in the margin of safety as defined in the basis for any technical specification. (SORC 95-042)

IEC-3252, Pkg. 1 "Reracking of Spent Fuel Pool for Increased Storage Capacity" Rev. 3 - This DCP removes nine existing Exxon racks and replaces them with nine maximum density Holtec racks. This revision to the DCP is being made to: I) delete references to the Offset Tool; 2) clarify the rack handling procedure, and 3) address minor errors observed during Part A closure. This revision involves neither the addition, deletion or modification of any equipment designed to monitor or control plant systems or components. There is no reduction in the margin of safety as defined in the basis for any technical specification. (SORC 95-053)

2. Temporary Modifications (T-Mod)95-035 "Temporary Blank for 1VHE838" Rev. 1 - 1VHE57, 12 Switchgear Ventilation Supply Fan and Motor are to be removed for maintenance. To support this activity, the filter plenum, 1VHE838 must be isolated. There is no isolation point on the upstream side of the fan. There is only one on the downstream side. Therefore, the upstream side is to be blanked off The temporary blank is to be constructed from safety related steel, with a thickness equivalent to or greater than that required of the plenum. The blank will take the place of the current nozzle, there is no loading on the existing nozzle area; immediately downstream is a rubber expansion joint.

Therefore, no seismic loading contribution exists. The .

modification involves neither the addition, deletion or modification of any equipment designed to monitor or control plant systems or components. There is no reduction in the margin of safety as defined in the basis for any technical specification. (SORC 95-051)95-036 "Temporary Blank for 1VHE838" Rev. 1 - 1VHE58, 13 Switchgear Ventilation Supply Fan and Motor are to be removed for maintenance to replace a bad motor. To support this activity, the filter plenum, 1VHE838 must be isolated.

There is no isolation point on the upstream side of the fan.

There is only one on the downstream side. Therefore, the upstream side is to be blanked off The temporary blank is to be constructed from safety related steel, with a thickness equivalent to or greater than that required of the plenum. The blank will take the place of the current nozzle, there is no loading on the existing nozzle area; immediately downstream is a rubber expansion joint.

3. Safety Ev~luations (S/E)

WO 950513085 "Freeze Seal of 13 Charging Pump Relief Valve Tailpipe" Rev.

0 - The purpose of this proposal is to install a freeze seal on the downstream piping of the Reciprocating Charging Pump discharge relief valve ICVl41. The freeze seal is needed to allow .the replacement of the relief valve. The freeze seal will prevent fluid from leaking out of the Volume Control Tank (VCT) while the valve is being replaced. In addition, the freeze seal will block any fluid should relief valves ICVl24 and I CV253 lift or leak by their seats. However, their relief path will not be affected by the freeze seal. The Chemical and Volume Control System (CVCS) will continue to be operated in accordance with normal operating procedures. At no time during the maintenance evolution, will the requirement that at least one boration injection flow path be available be challenged: The flow path from either Boric Acid Tank or Refueling Water Storage Tank to the Reactor Coolant System (RCS) will not be affected by the proposed activities. The margin of safety as defined in the bases for the technical specifications will not be reduced. (SORC 95-052)

4. Deficiency Reports (DR) Us~-As-Is DRDSI.8-0010/ "DR 950501234 "V5H Fuel Grid Mxing Vanes" Rev. 0 - This safety evaluation is being written to provide a use-as-is disposition to DR 950501234 which documents the non-conforming condition which presently exists in the V5H fuel loaded at Salem Units 1and2. During the manufacturing of the 17 x 17 fuel assembly grid straps, the mid-grid mixing vanes were under bent. Westinghouse has since determined that the mean production vane angle for the as loaded Salem VHS fuel assemblies could be as much as 2.2° less than the mean angle in place during design basis DNB testing. Since the vanes are under bent, there is no risk of mechanical contact with a fuel rod. Westinghouse has concluded that the under bent vanes do not adversely affect the mechanical or structural integrity of the fuel assemblies. Westinghouse has determined that a conservative evaluation of the under bent mixing vanes results in a 1.9% DNBR penalty. Since sufficient DNBR margin still exists, no safety limits have been violated and the conclusions of the UFSAR Chapter 15 accident analyses remain valid. The change in vane grid angle does not result in changing any fuel related limits or design failure points. Although generic DNBR margin is affected by this change, the limits as defined by any technical specification basis are not affected. Hence the margin of safety is preserved. (SORC 95-042)

SALEM GENERATING STATION MONTHLY OPERATING

SUMMARY

- UNIT 1 MAY 1995 SALEM UNIT NO. 1 The Unit began the period operating at 94% power and continued at that level until 5/4, when load was reduced to 50% to support replacement of both Steam Generator Feedwater Pump (SGFP) governors. A power increase was initiated on 5/14, following completion of SGFP

. post maintenance testing. On 5/15, the power increase was stopped at 60% due to concerns over operability of equipment serviced by #12 & 13 switchgear supply fans. The #13 fan motor had failed on 5/14, and #12 had been out of service due to a failed motor bearing. The appropriate justification for continued operation with only one fan could not be obtained and a conservative decision was made to shutdown. The Unit was removed from service on 5/17, and remained shutdown throughout the rest of the period.
